There are also folks who just plain disagree. Some can’t distinguish the two.
***It’s easy. Trolls admit they get “entertainment” from throwing bombs on issues like this. Trolls disregard facts that have been posted directly to them when they continue to spout talking points straight from DU. Trolls like to insist that the burden of proving a negative is on us rather than the burden of proving eligibility is on the candidate, like the constitution says. Trolls use logical fallacies right and left, and don’t bother to correct the usage. There are other distinctions, I’m sure, but those are the ones I use.
Then you are the exception, not the rule.
